BITS_PER_LONG used in include/asm-generic/statfs.h

[H.J. Lu]

Hi,

include/asm-generic/statfs.h has

#ifndef __statfs_word
#if BITS_PER_LONG == 64
#define __statfs_word long
#else
#define __statfs_word __u32
#endif
#endif

however, BITS_PER_LONG isn't defined when asm-generic/statfs.h is exported to
user space.  Shouldn't it check __BITS_PER_LONG instead, at least when
exported to user space?
